I'm not sure exactly what reparations you're thinking will be possible by rolling back a DDL transaction. I'm pretty sure most db's don't have full transaction control over DDL. Issuing a DDL statement usually involves at least an implicit commit, so, e.g., if something goes wrong three DDL commands into your evolution you're not going to be able to roll back to initial state. Backing up the db before the series of DDL statements is only sure way to guarantee a rollback for all db's, I think. -- Herb --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django developers" group.
